Faber Miles (Milanise7en) added a comment to T50856: Blender is not responding after minimizing [AMD].

Problem has not been fixed for me. It still flickers and stops responding everytime i click something and crashes whenever i minimize. I'm using latest 2.79 and a Radeon Vega 64.

Thank you for the report. Currently we are aware of many issues in 2.8 and actively working to fix them. But since replying to reports takes time, we have decided to limit bug reports to module team members.

alekulyn reopened T48880: "Failed to build shader variant" error on open-source amd drivers. as "Open".

I'm getting the same error on a AMD 5800K APU, which has the Radeon HD 7660D GPU, on startup in 2.8. The default cube displays, but its shader is just a bunch of random noise. I should mention that this only occurs with Eevee, and not any of the other render engines.

alekulyn added a comment to T51576: Blender crash when change to edit mode with Intel GPU.

Getting the same issue here on Linux with an AMD 5800K APU. Apparently, gpu_basic_shader is returning a null pointer which gets passed to GPU_shader_get_uniform, which then tries to point/access elements in that structure, resulting in a segfault.

Sergey Sharybin (sergey) closed T53468: Material viewport shading mode doesn't respect the "clip" image texture setting as Archived.

Thanks for the report, but this is a known limitation since initial Clipping implementation in Cycles: for GLSL e really need to use OpenGL clipping, which is fast but which would requite some internal changes in how we work with OpenGL textures. Currently, we only use one OpenGL texture per image, which will cause unpredictable results if the same image is used with different clipping/extension methods.

Its highly likely that this bug is specific to your hardware/driver configuration. These kinds of display issues are often caused by OpenGL driver bugs.

Sorry, but I have to reinstall Linux and resolve this problem, because the cause is the crashes in linux caused by inflated software that i dont support any more, and the single-core prosessor is more insufficient for editing armatures in blender

@Dalai Felinto (dfelinto) does this mean that we simply want to do a single frame render in the largest available area region (like in 2.79) using whatever 2.8 engine is configured for the current scene or is there more to this?

Changing the Selection Method to Occlusion Queries under User Preferences > System may work around the issue. In Blender 2.8 this will likely become the default (and only) method.

The back trace in report indicates crash somewhere inside of Mesa/LLVM. We can not fix that or patch from Blender side, the driver itself is to be brought to a state when it can handle complexity of Cycles kernels.

I understand this is not a Blender issue, however six months after the various bugs were filed, Blender 2.79 still crashes on compilation under Ubuntu 17.10 Beta 2 with LLVM 5.0 and Mesa 17.2.2, even though it appears to me that all reported bugs were fixed.
